' s claims. (o1. 242,-7146)y {Thisinvention relates to improvements in a threadY package adapted to be sold as an article of manufacture comprising a container having therein a tube of shoe thread or thelike which s will protect the thread from injury and from the absorption of moisture Aduring storage and shipment and which can be conveniently ymounted upon the spindleof a sewing machine orother suitable supporting stand andV fromv which the thread may beprogressively delivered'freely. and without knking.

The invention is particularly adapted for use in connection with heavy threads such as shoe threads which are employed in stitching machines, but which may be employed With lighter forms of thread vsuchas linen, silk, and thezlike.

It is Well known that if thread becomes too` dry the tensile strength is materially reduced, and such drying of the thread often occurs Where the thread tubes are'kept in proximity tostearn pipes, radiators, etc., or in heated storage compartments, and one of'theobjectsofithe invention is toprovide a/simple and economical threadpackage in which evaporation of the moisture content of the thread will be minimized and which willfprotect the thread package fromgrease and dirt yWhich occurs When'the thread package isihanclled or oil splashed upon the thread from the machine on which it is being used. Y Y u It is very important to prevent the thread from becoming oily as the oil prevents ythe Yproper absorption of Wax when usedin stitching leather and interferes Withthe uniformity of the strength of the thread which is increased by the application of the Wax.

An important feature of the invention resides in the production of a thread package comprising a casing of preferably moisture-proofed fibrous material, such as cardboard, containing a thread package Wound upon a single-head spool, the head of which is of .greater diameter than the diameter of the thread package and enclosed in a casing of fibrous materialv the bottom of which is permanently secured to the spool head, the cas ing being of suiliciently large diameter and height to permitV free unwindingof the thread as it is pulled'through a central delivery aperture in the cap orcover of the casing.

These and other objects and features of the invention will more fully appear from the following description and the accompanying drawing iand will be particularly pointed out in the claims. In the drawing: y Y `lig. 41J is averticaldiametrical sectional viewof a preferred form of thread packagefembodying' thezinvention; Y Y

Fig. -5 is a similar view upon a larger scale-showingl the parts in vertical sectionV and illustrating a spinning tool engaging and crimpinggthe lower end-'of the core Yover the bottom of the casingand thespool head. l Y

, The preferred form of thread package illustrated in Fig. 1 comprises a container having-a cylindrical Wall I of fibrous material, preferably cardboard, provided atfitslower end with a bottom 2 having a peripheral flange 3v fitting-the lower end of the casing Iy yand secured thereto by glue or other adhesive. The bottom 2f is.v provided with a central opening f4 through which the core of a single-head spool projects and is securely fastened, preferably by being spun, over 4the bottom by asuitable tool 5, .as illustrated inFig. 5. This casing contains a tube of thread 6 vofsu'liiiciently smaller diameter than the casing, to permit the thread Lto be freely unwound therefrom. `The thread is wound upon a single-hea'dl-spool'having ahead 'l which closely tsw-ithin the casing with itslower face secured to thevbottornr2 by vglue :81, or other suitable material, theperiphery ofgthe head 'lbeing also glued to the casing I. The single-headspoolhas a tubular core ID'the'lOWer end4 Il of Which-projects through thespoolhead and preferably also the bottom 2gof Vthe casing and ispermanently secured thereto-by beingspun over theheadandbottom after the tube of Athread. is assembled Within the casing. Thetub-ular core isV previously glued to the spoolhead 1.

It has .heretofore been deemed diicult if not impossible towind a cylindrical'tube of thread .upon aspool in such .manner ,that-the flat end Vof the thread Will abut the spool head, butmeans have 'been devised by theapplicantjvvhich will permit the winding of the tube of thread in overlapping layers with the lower end of the thread tube contacting with the spool head I throughout its entire area and which is wound in such manner that the thread will readily unwind from the periphery of the thread tube toward the core.

The upper end of the core is closed by a plug I2 which fits tightly in the upper end of the core and preferably is flush with the upper end of the core. The upper end of the casing extends well above the upper end of the tube of thread to provide an ample space I3 which, together with the annular space I4 between the periphery of the n tube of thread and the wall of the casing will permit the thread to be readily unwound from the tube of thread when it is pulled throughra delivery opening located substantially axially of the thread tube.

The upper end of the casing is closed by a cap I5 having an annular flange I6 which ts tightly upon and preferably is glued to the upper end of the casing. The cap I5 is provided with a central opening preferably protected by a metal eyelet or grommet I'I forming a delivery passage for the thread I8. The cap desirably is provided with one or more sight openings which are covered by a layer of transparent material I9. lThe casing I and the cap I5 desirably are moistureproofed as by the spraying upon the interior thereof a coating 2li of paran or other waterrepellent material, or by a lining of cellophane or like material. In the latter case the cellophane may be employed to cover the sight openings.

The delivery opening desirably is sealed by a disk 2l of suitable waterproofed material having an adhesive under surface which may be moistened and applied to the cap in such manner as to cover the delivery opening and also to retain the end of the thread I8 during storage and transportation.

By reason of the construction above described the moisture-proofed casing and cap together with the plug I2 prevent the escape of the normal moisture content of the thread from the tube of thread during storage and transportation. When the thread package is to be used upon a sewing machine the tubular core is placed upon the spindle and the end of the thread I8 drawn upwardly thereby disengaging the seal 20 and permitting the thread to be progressively drawn from the tube of thread. Inasmuch as the delivery opening is well above the end of the tube of thread and suflicient space provided between the periphery of the tube of thread and the wall of the casing, vthe thread will readily unwind from the casing, but will be prevented from ballooning to such an extent as to kink the thread.

While in the particular embodiment of the invention illustrated herein the tube of thread is shown as of cylindrical form wound upon a spool having a fiat head, it will be understood that the tube of thread may be wound upon the tubular core and the end of the wound core then inserted through the registering holes in the spool head and the bottom of the container and spun over as heretofore described. It will also be understood that the head of the single-head spool may be of conical form with the periphery of the head xedlysecured to the casing, or that other modifications of the invention may be made within the meaning and scope of the following claims.
